Title: Improvements in or relating to electrical signalling systems
IPC: H04B1/58
Filed: 1945-04-04
Abstract: 589,784. Anti-side-tone circuits. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. April 4, 1945, No. 8339. Convention date, April 4, 1944. Drawings to Specification. [Class 40 (iv)] An arrangement for coupling a four-wire system to a two-wire line, particularly a transportable installation, intended for connection to one of several different lines communicating with a radio station, there is included in one or both branches of the four-wire system an adjustable attenuating network, the adjustment of which is mechanically coupled to the control for adjusting the balance network of the hybrid transformer. This ensures that when adjustment is made to the balancing network to compensate for a line of particular length, simultaneous adjustment is made to the speech circuit to maintain the signals at a constant desired level.

Abstract: 1,027,047. Machine for taping cores. WINN & COALES Ltd. Feb. 28, 1964 [March 1, 1963], No. 8393/63. Heading B8G. [Also in Division F2] A device for helically wrapping pipes or like elongated members of circular section comprises an annular member 14 having a removable or hinged segment, said member mounting one or more tape reel supports 6, and carrying a plurality of pairs of progression wheels or rollers 1 circumferentially spaced around the annulus by not more than 180 degrees, the wheels of each pair both being spaced apart along, and having their axes of rotation inclined to, the axis of the annular member. Each pair of wheels is housed in a member 2 carried by each of three equally spaced radial rods 3, said rods being rotatably and radially adjustable in clamps 4 whereby the rate of advance of the annular plate on rotation may be varied and whereby pipes of different diameters may be accommodated. The extent of radial adjustment is indicated by circumferential grooves around the rods. The wheels of each pair, which may be of rubber or steel, are staggered unequal distances a, b from their rod axes, the respective distances for other wheel pairs being varied such that on rotation of the plate 14 the wheels cross a given pipe circumference in succession. Alternatively, the distances a, b may be constant and the clamps axially staggered. The two segments of the plate 14, hinged at 9, are clamped by hook 10a of an over centre-toggle-link 10 on one segment engaging projections of a spring-loaded rod 13 sliding in a boss 12 on the other segment, thereby causing the pairs of progression wheels to be pressed against a pipe 7. Each wheel pair may be individually spring-loaded against the pipe and each housing may be rockable on its rod.

Title: Improved process for desizing and rapidly degumming fibres or fabrics
IPC: D06L1/14
Filed: 1924-04-04
Abstract: For de-sizing and rapidly de-gumming fibres and fabrics, the materials impregnated with a solution of diastase, pancreatin and like de-sizing substances, are subjected to a sudden rise of temperature to about 90-100 DEG  C.  The heating may be effected by passage through a heated chamber, or through a medium having no solvent action on the de-sizing solution, or by passage over a heated surface.

Abstract: 1,157,767. Priming centrifugal pumps. H.J. GODWIN Ltd. Feb. 22, 1968, No. 8706/68. Heading F1C. A pump is primed by withdrawing air from the pump inlet duct into a vent passage by passing air under pressure through the vent passage to entrain the air. In the centrifugal pump shown, an ejection 10, which may be energized by a compressor 15 driven by the electric motor or I. C. engine which drives the pump, withdraws air from the suction chamber 5 of the pump to a vent passage 7, a non-return valve in the pump outlet duct preventing air from being drawn therethrough in a direction towards the pump. The small amount of liquid which passes through the vent passage 7 at times when the pump does not require priming may be allowed to run to waste. Alternatively, a chamber 11 may be provided, having a vent port 12 for the escape of the air and a port 13 under the control of a float valve 14 for the return of the liquid to the pump inlet duct 3.

Abstract: 581,492. Conductors. PIRELLI-GENERAL CABLE WORKS, Ltd., and BARRON, H. May 15, 1944, No. 9238. [Class 36] [Also in Group XXXV] In providing wire with an electrically insulating coating of polyvinyl acetal, polyvinyl formal, or synthetic linear polyamide, the first coats are subjected individually, or collectively as a final step, to a baking temperature high enough to render the coatings infusible by heat, and a final coat, subsequently applied, is heated to a drying temperature much lower than the baking temperature, sufficient only to remove solvent and render the coating non- sticky at ordinary temperature, without affecting its property of softening and becoming self-adhesive under heat. The under layers may be heated to 450‹C. and the final layer dried at 250‹C. Coils wound from the coated wire may be heated in an oven, by radiant heat, or by passing an electric current therethrough, to render the outer coating soft and adhesive so that adjacent turns adhere to one another.

Filed: 1929-03-22
Abstract: 332,605. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 22, 1929. Vinyl ethers are obtained by treating vinyl monohalides, or homologues thereof containing at least one hydrogen atom connected to the carbon atom of the double bond which is free from halogen, with aliphatic, cycloaliphatic, or aliphaticaromatic alcoholates or phenolates in the presence of organic diluents. Instead of alcoholates, mixtures of alcohols with oxides or hydroxides of the alkali or alkaline earth metals may be employed. Mixtures of different alcohols or alcoholates may be used as starting materials. Suitable diluents which dissolve the reaction componest are alcohols, preferably those corresponding to the alcoholates employed, or phenols. Suspending agents, for example, hydrocarbons, may also be used. The reaction may be carried out under atmospheric pressure or in a closed apparatus, or inert gases such as methane, nitrogen, or hydrogen may be introduced under pressure into the reaction vessel. Non-acid dyeing agents such as quicklime, anhydrous sodium sulphate, copper sulphate, or potash may be present. Examples are given describing the preparation by the above methods of vinylmethyl ether, vinylethyl ether, vinylbutyl ether, vinyl phenyl ether, vinyl-ocresyl ether, vinyl-m-cresyl ether, vinyl-alpha-naphthyl ether, vinyl-#-naphthyl ether, ethylisopropenyl ether, and ethyl-1 : 2-dimethylvinyl ether. 2-Chlor-#-butylene, which is used in the prepartion of ethyl-1 : 2-dimethylvinyl ether, is obtained by splitting off hydrogen chloride from 2: 3-dichlorbutane by means of alcoholic potash.
